ISRO to launch 7th navigation satellite on April 28
India is slated to put into orbit its seventh and final navigation satellite on April 28, thereby having its full satellite navigation system up in the sky, said a senior space agency official. “The launch of India’s seventh and the final in the series of satellites will be on April 28 afternoon. The IRNSS-1G (Indian Regional Navigation Satellite System-1G) will be put into orbit by our rocket Polar Satellite Launch Vehicle (PSLV),” K.Sivan, director, Vikram Sarabhai Space Centre of the Indian Space Research Organization (ISRO), told IANS.
The PSLV rocket will blast off after 12 noon on April 28 from India’s spaceport at Sriharikota in Andhra Pradesh. Till date, India has launched six regional navigational satellites (IRNSS-1A, 1B, 1C, ID, 1E and 1F) as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500 km.
Though the full system comprises nine satellites — seven in orbit and two on the ground as stand-by, the navigation services could be made operational with four satellites, ISRO officials had said earlier. Each satellite costs about Rs 150 crore while the PSLV-XL version rocket costs about Rs 130 crore. The seven rockets would entail an outlay of about Rs 910 crore.
